Effect of SQLXF on the left ventricular functions of CHF rats. CHF rats were treated with low-dose (8.48 g/kg/day), middle-dose (16.96 g/kg/day), and high-dose (33.92 g/kg/day) SQLXF, respectively. A LVSP in all rats was measured. B LVEDP in all rats was examined. C + LVdP/dtmax in all rats was measured. D −LVdP/dtmax in all rats was measured. E Concentration of LDH in the serum of all rats was measured using LDH detection kit. F Concentration of CK-MB in the serum of all rats was examined using a specific kit. G ELISA assay was carried out to detect the concentration of BNP in the serum of all rats. **P < 0.01 compared with Sham group. ^#P < 0.05 and ^##P < 0.01 compared with Model group
